The mechanism from when the exchange receives the pager communication message code by the push button signal to when the message is displayed on the other party's pager is already known and is not the gist of the present invention. The description is omitted.

The state of the data stored in the read-only memory 7 will be described with reference to FIG. FIG. 4 is a diagram showing a data storage state of the read-only memory 7.

The address of the read-only memory 7 matches the counter value of the counter circuit 6. Data outputs D7 to D0 from addresses 000 to 009 of the read-only memory 7
"LLLLLLLLL" is written in the address, and "LLHLLLLH" is written in the data outputs D7 to D0 of the address 010.
L ”is written. Hereinafter, "LLHLLLLLH" is output to the data outputs D7 to D0 of the address 011 and "LHLLLLLL" is output to the data outputs D7 to D0 of the address 012.
“H” has been written, and “LLHLLHLL” has been written to the data outputs D7 to D0 at address 017. Note that L and H are signal level "Low", respectively.

The correspondence between the input signal and the output signal of the PB signal generation circuit 8 will be described with reference to FIG. FIG. 5 is a diagram showing the correspondence between the input signal and the output signal of the PB signal generation circuit 8.

When the signals "LLLHLLLLH" are applied to the inputs C4 to C1 and R4 to R1 of the PB signal generation circuit 8, the push button signal "1" is output to the output OUT, and the PB signal generation circuit 8 outputs the signals. When the signals "LLHLLLLLLH" are applied to the inputs C4 to C1 and R4 to R1, the push button signal "2" is output to the output OUT.

Next, the operation of the apparatus according to the first embodiment of the present invention will be described.

When the activation signal from the monitored system in which the failure has occurred is received at the activation signal input terminal 1, the timing control circuit 10 is activated. The timing control circuit 10 drives the off-hook relay coil 4, closes the off-hook relay contact 5 and connects the response monitoring circuit 3 to the output terminals 13 and 13 'to form a DC loop, and makes a call to the telephone exchange. Send a signal. In addition, the timing control circuit 10 outputs the output of the clock generation circuit 9 at a periodic rate suitable for sending a push button signal, for example, 100 ms make, 10
It is converted into a clock signal of 200 ms cycle of 0 ms break and supplied to the input gate EN of the counter circuit 6.

The counter circuit 6 produces a signal (counter outputs Q0 to Q6 in FIG. 1) which is counted down to the number of outputs corresponding to the number of address inputs of the read-only memory 7, and supplies it to the address inputs A0 to A6 of the read-only memory 7. To do. Receiving the signals of the counter outputs Q0 to Q6 of the counter circuit 6, the addresses of the read-only memory 7 are continuously designated, and the stored data outputs D0 to D7 written in advance are read out. The read data in the read-only memory 7 is P
Inputs R1 to R4 and C1 to C4 of the B signal generation circuit 8 are supplied, and push button signals corresponding to the input signals are output.

The counter value of the output signal of the counter circuit 6 is 000 at the beginning, and the address 000 of the read-only memory 7 is displayed.
Since the data written in is "LLLLLLLLL", the push button signal is not output from the PB signal generation circuit 8 due to this data. Further, when the counter value is 001 to 009, the output of the corresponding read-only memory 7 is "LLLLLLLLL", and the push button signal is not output. This is a guard timing from when the telephone exchange detects a call from the automatic emergency contact device to when it is in the dial signal receiving state, and it secures about 2 seconds.

When the counter value of the output signal of the counter circuit 6 becomes 010, the data written in the address 010 of the read-only memory 7 is "LLHLLLLHL", and therefore the push button signal " 5 "is output, but the transmission time of this push button signal is the input gate E of the PB signal generation circuit 8.
The signal applied to N is output only during "H", that is, 100 ms which is the make time of the clock signal.
Is only output.

Next, the counter value of the counter circuit 6 is 01.
When it becomes 1, the data "LLHLLLLH" of the address 011 of the read-only memory 7 is read, and the push button signal "2" corresponding to the data is output from the PB signal generation circuit 8. In the same manner, data of consecutive addresses in the read-only memory 7 corresponding to the counter value of the counter circuit 6 is read out, a push button signal corresponding to the data is output from the PB signal generating circuit 8, and the counter circuit 6 The data of the address of the read-only memory 7 corresponding to the counter value 017 of is read out, and the push button signal “8” corresponding to the data is sent from the PB signal generation circuit 8.

The output of the counter circuit 6 is the counter value 017.
When it reaches, the signal output gate CK of the counter circuit 6 sends a signal to the timing control circuit 10, and the timing control circuit 10 suspends the supply of the clock signal to the counter circuit 6 and suspends the counter operation of the counter circuit 6.

During this period, the output OUT of the PB signal generation circuit 8
The series of pushbutton signals output from the transformer 1
1, the DC blocking capacitors 12 and 12 ', the off-hook relay contact 5, the output terminals 13 and 13', and the telephone line to the telephone exchange.

When the exchange receives the push button signal, it identifies the dialed number and immediately connects to the pager system when the called party determines that it is a pager subscriber number. When the pager system responds, a response signal (polarity inversion signal) is returned from the exchange through the telephone line to the device of the first embodiment of the present invention, and the pager system side sends a guidance prompting for message code input. ..

When the response monitoring circuit 3 detects the response signal sent from the telephone exchange, it notifies the timing control circuit 10 of the detection result, and the timing control circuit 10 restarts the supply of the clock signal to the counter circuit 6. The counter circuit 6 receives the restarted clock signal and restarts the counter operation.
Up to 66, the data output of the corresponding read-only memory 7 is "LLLLLLLLL", and the push button signal is not output. This is a guard timing for stopping the transmission of the push button signal during the guidance prompting the message code input sent from the pager system side, and corresponds to about 10 seconds.

Next, when the counter value reaches 067, the data "LLL" at the address 067 of the read-only memory 7 corresponding to the counter value becomes 067.
"HHLLLL" is read out, and the push button signal "*" corresponding to the data is 100 m from the PB signal generation circuit 8.
It is sent out only for s, and the counter value 068 indicates "LLHLH
“LLL” is read out, and the push button signal “0” corresponding to the data is transmitted. Thereafter, data of consecutive addresses in the read-only memory 7 are read in the same manner,
A push button signal corresponding to the data is sent from the PB signal generation circuit 8. With the counter values 074 and 075, the data "LHLLHLLL" and "LH" of the read-only memory 7
LLHLLL "is read, and a series of operations continues until pushbutton signals"#"and"#"corresponding to the data are sent.

"#" And "#" are end symbols of the message code of the pager, and when the pager system receives this signal, it sends a communication message designated by the pager of the other party and is displayed on the display of the pager of the other party. The message “There was an accident, please gather at the company immediately” is displayed.

On the other hand, when the device of the first embodiment of the present invention sends the corresponding push button signal "#" with the counter value 075, the timing control circuit 10 stops the supply of the clock signal to the counter circuit 6, and the counter circuit 6 Is reset, the driving of the off-hook relay coil 4 is stopped, and all the operations of the device of the first embodiment of the present invention are completed. When the off-hook relay contact 5 is opened, the response monitoring circuit 3 is disconnected from the output terminal 13 and the direct current loop to the telephone exchange is released. Therefore, the telephone exchange side determines that the call has ended, and the connection operation inside the telephone exchange ends. To do.

Further, in the apparatus of the first embodiment of the present invention, the case where one kind of message is sent to one partner subscriber in response to one start signal has been described, but in response to a plurality of start signals, It is also possible to send different messages to a plurality of partner subscribers. This will be described as a second embodiment device of the present invention.

G corresponds to the address inputs A7 to A13 of the read-only memory 7, respectively. The OR circuit 14 converges the activation signal and connects it to the timing control circuit 10.

When the start signal is received at any of the start signal input terminals 1A to 1G, the start signal is sent to the timing control circuit 10 via the OR circuit 14. The timing control circuit 10 is activated, and the timing control circuit 10 drives the off-hook relay coil 4 and the off-hook relay contact 5 and simultaneously operates the counter circuit 6. The counter outputs Q0 to Q6 of the counter circuit 6 and the activation signal input terminals 1A to 1G specify the address of the read-only memory 7. That is, among the activation signal input terminals 1A to 1G, only the terminal that receives the activation signal has the signal level "H" and the others have the signal level "L", and the activation signals of these activation signal input terminals 1A to 1G are read-only. By connecting to the upper address of the memory 7, the addresses 0128 to 020 of the read-only memory 7 are connected.
3 stores the data of the message corresponding to the destination subscriber number corresponding to the activation signal input terminal 1A. Further, the addresses 0256 to 0331 of the read-only memory 7 store the data of the message corresponding to the destination subscriber number corresponding to the activation signal input terminal 1B, and the activation signal is input to the addresses 0512 to 0587 of the read-only memory 7. The data of the message corresponding to the destination subscriber number corresponding to the terminal 1C is stored.
Stored in 192 to 9267 are message data corresponding to the destination subscriber number corresponding to the activation signal input terminal 1G.

For example, when the activation signal input terminal 1C receives the activation signal, the signal level of the address input A9 of the read-only memory 7 is "H" level, the address inputs A7 to A8,
The signal level of A10 to A13 becomes the "L" level, the data of the address of the read-only memory 7 is sequentially read from 0512 according to the output of the counter output Q0 to Q6 of the counter circuit 6, and the preset start signal input terminal is set. The destination subscriber number corresponding to 1C and the message data corresponding thereto are read. The subsequent operation is similar to that of the first embodiment device of the present invention, and therefore the description thereof is omitted.

When changing the subscriber number for calling the pager of the other party, it is sufficient to write the new subscriber number in a new memory and replace it with the old memory. It is possible simply by replacing the message with the new memory.

If the destination subscriber number is registered as the abbreviated number of the telephone exchange that houses the device of the present invention and the abbreviated number is transmitted from the device of the present invention, the other party The previous change does not need to rewrite the data in the memory, but only needs to re-register the abbreviated number from the telephone connected to the telephone line.
